A sheet extrusion line quotation is easier to compare when every supplier uses the same product and performance basis. Use this plastic sheet extrusion line checklist before you approve equipment scope, output or price.
Sheet and board extrusion lines are capital projects with a long operating life. A quotation is useful only when every supplier describes the same product, scope and performance basis.
1. Define the finished product
State the material, width, thickness, layer structure and target output. If the sheet will be thermoformed, laminated, printed or cut, include those downstream requirements.
2. Separate equipment from performance
A list of extruders and rolls is not a performance promise. Ask for line speed, thickness tolerance, scrap assumption and finished output at the quoted size.
3. Check the interface scope
Confirm who supplies the chiller, compressed air, power distribution, silo, installation, commissioning and operator training.
4. Compare control and instrumentation
Check gravimetric dosing, melt pressure control, automatic die adjustment, thickness gauging, recipe management and remote diagnostics.
5. Review wear and spare parts
Screw, barrel, screen changer, die lip and roll surface condition determine long-term maintenance cost. Request a recommended spare-parts list.
6. Verify the acceptance method
Define empty run, material trial, continuous production, thickness measurement, output verification and documentation.
7. Ask for a total project view
Compare floor space, utility consumption, installation time, operator count, material yield and expected maintenance.
A strong quotation is transparent enough that two suppliers can be compared line by line, not just price by price.
